Internuclear ophthalmoplegia following radial artery cardiac catheterization approach: An unusual presentation.

Internuclear ophthalmoplegia (INO) may happen following percutaneous coronary intervention and angiography. However, no reports of INO during radial artery angioplasty were reported yet. We report a rare case in a 47-year-old man presenting with diplopia after radial artery angioplasty. Although the symptoms were resolved after 60 days, diagnosing this obstacle is necessary to reduce the patient and physician's anxiety.
